' LOADING OR UNLOADING APPARATUS.

SPECIFICATION forming part of Letters Patent N o. 741,538, dated October 13, 1903. Application filed March 31, 1903.V Serial No. 150,355. V(Noy model.) l

To all whom it may concern/.- g

Be it known that 1.1 ULEs ALBERT PAsrU- REAU, a citizen of the United States, and a resident of Laplace, Yin the parish of St. John the Baptist and State of Louisiana, have in- VVented a new and Improved Loading or Unloading Apparatus, of which'the following is ciple object of my invention is to provide an apparatus of this kind which is simple both in the construction and organization of the several parts or elements thereof, besides being thoroughly effective and reliable in operation and possessing the capacity for long and repeated service.

A further object is to provide an apparatusl formed thereby.

The above and additional objects are obtained by means substantially such as are illustrated in the accompanying drawings, in which- Figure 1 is an end elevation of my improved apparatus looking at the same from the rear. Fig. 2 is a vertical sectional elevation taken on the line a; x in Fig. 1. Fig. 3 is a side elevation of the upper part ofthe apparatus shown in Fig. 1 lookin g toward the left of said latter figure. Fig. itis a top plan view of a part of the apparatus shown in Fig. 1, and Figf is a sectional-plan View taken on .the line y y in Fig. 1. v

` Preliminarilyto a more detailed description it may be stated that in order to render my improved apparatus portable or capablework of any desired height, as well as hoist- A ing mechanism of special embodiment, combined with a trackway, also of special embodiment, whereby a load may be elevated or raised from one point or location and transferred to another point or location, where the same may be dumped or deposited. I- employ a simple and effective structure, as will be hereinafter more fully explained, and while I have herein represented a certain preferred form or embodiment of my inventionv it will be understood that l am not limited to the precise details thereof in practice, since immaterial changes thereinv may be resorted to coming within the scope of my invention.

Specific reference being had to the drawings by designating characters marked thereon, 1 represents the platform of an ordinary wheeled vehicle or truck having suitable means for the connection therewith of a horse or a team of -borses for the purpose of propelling the same, as indicated at 2 and 3, for instance, and mounted upon said truck and rmly held in position in any suitable way, as by means of the bracesd 4 and 5 5, is a vertical rectangular structure comprising, preferably, four standards or uprigbts 6, and suitably secured to and supported by the said standards or uprights at theV upper parts of the latterisa of vertical connecting-sections, (indicated at 8,) these latter being also united by means'of braces 9 10, extending substantially parallel with the sides of the .truck or vehicle,as shown. The said upper right-angled frame structure referred to is provided with an inclined way extending longitudinally of said structure, but transversely of the truck, said Way preferably comprising two rails12, inclined downwardly from -a point indicated at 13 inFigs. 1 and 5 to a point 14in said figures, it being observed froln the latter ligure that the said rails 12 are curved around at 15, so astobring the lower terminal thereof some distance to one side of the general direction of the rails, although, ifv desired, the rails may be perfectly straight throughout, as is apparent. The said rails 12 are each formed in two sections, as shown in Figs. 1 and 5', the adjacent IOC ends of these sections being pivoted or otherwise movably joined together, as by means of side plates 16, secured at 17 to the sides of one rail-section and having pivots 18 passed therethrough and through corresponding openings therefor near the adjacent ends of the other section, it being apparent that in this way the lowermost inclined sections of said rails may be raised and lowered with respect to the uppermost sections thereof, these latter sections being stationary and maintained at the desired inclination by means of hangers 20 pendent from the uppermost bars or beams 7 of the elevated frame structure of the apparatus. At the upper end of the stationary sect-ions of the inclined rails is what I term a boot or guide, constituted of parallel vertically-disposed side plates 2l,havinginclined flange portions 22,alining with the said upper ends of the stationary rail-sections, and secured to said iiangcd portions at 23 are the upper ends of duplicate cables or ropes 24, in bights of which are supported grooved wheels 25 of a trolley device or loadcarrier 26, having pendent therefrom a hook or other attaching device 28, upon which may be hung or suspended either a load to be elevated and transported or a bucket or other vessel for containing the load. As shown in Fig. 1, after leaving the grooved wheels 25 of the trolley device the said duplicate cables or ropes 24 pass upwardly overguide-pulleys 29 therefor, from whence they pass to similar guide-pulleys 30,each supported by the framework of the apparatus, and the other ends thereof .are secured at 31 also to the framework. A loop 32 is formed in each of these cables, and suspended in said loops is a pulley 33, attached to the frame of which is a hook 34, to which in turn is attached a pulley-block 35, said pulley-block having a ring or pulley 36, Fig. 3, and fastened to said ring 36 is one end of a cable or rope 37, which passes down and through a double pulleyblock 38, supported in brackets 39 on the underside of the platform of the truck. Thence said cable or rope extends upwardly again at 40 to and through the pulley-block 35, whence the rope again passes downwardly at 41, and,

finally through the other side of the said double pulley-block 38 at 42, the end thereof being permanently fastened at 43. Carried in a loop 44 of said cable or rope is a pulley 45, to the frame of which is connected a hook 46, to which in turn any suitable form of draft appliance may be applied for connection of a horse or other animal, whereby may be effected the elevation of a load to be transferred, as will presently appear.

At the lower terminal 14 of the movable sections of the inclined rails 12 al yoke 47 is employed, in which the ends of said rail-sections are supported, and connected to said yoke is one end of a cable or rope 48, which passes upwardly over a guide-pulley 49 therefor supported by a portion of the framework ofthe apparatus, this cable or rope thence passing inwardly and over another guidepulley 50, whence the cable or rope passes downwardly and has attached to the other end thereof a counterbalancing device 51, (see Figs. 1, 2, and 3,) the weight of which is sufficient to normally maintain the movable rail-sections in the upwardly-inclined position thereof. (Indicated in dotted lines, Fig. 1.) In order to limit the upward movement of the said counterbalancing device 51, I preferably employ a stop 52, with which the device comes in contact at a point corresponding to the limit desired for the solid-line inclination of the said movable rail-sections. As before stated, the upright members and the horizontal members of the framework are preferably strengthened by the braces, and it may be mentioned that the ends of the upright horizontal frame structure are supported against the uprights or standards 6 by means of diagonal brace-rods 58, (see Fig. 1,) and other diagonal brace-rods are employed between adjacent ones of said uprights or standards 6, as indicated at 54. (See Figs. 2 and 3, for instance.)

The elements or parts of the apparatus being constructed and organized as hereinbefore explained, the load to be elevated and transported may be attached or connected in any suitable manner to the hook 28, carried by the trolley device orload-carrier 26, whereupon by causing a horse or other animal connected with the hook 46 to move outwardly from the apparatus the said cable or rope 374 will be caused to pay out as to its length, as is apparent, and this action results in so draw- `ing upon the duplicate cables or ropes 24 as to elevate the trolley device or load-carrier (together with theload) to a position between the sides 2l of the boot or guide referred to, and at this point of elevation the duplicate grooved wheels of the trolley device or load-carrier will pass from said boot or guide to the elevated ends of the stationary sections of the inclined rails 12, whence the said trolley device and its load will descend upon the said rails by gravity, and the weight of this traveling structure will cause the reversely-inclined movable rail-sections to be depressed from the dotted-line position thereof (shown in Fig. 1) to the full-line position, (shown also in said figure,) and in this way said load may be transferred to the point or place at which` it is desired to deposit the same. As soon as a load has been discharged or deposited the weight of the counterbalancing device 51 again elevates the movable rail-sections to the dotted-line position thereof, (indicated in Fig. 1,) whereupon the trolley device descends upon these sections in a reverse direction to that first taken thereby, and the velocity acquired by the said device in this descent thereof is sufficient to carry the same up the stationary inclined rail-sections to the boot or guide, at which latter place the grooved wheels of the trolley device or load-carrier again pass upon the du- ICO ITO

IIR

plicate cables or ropes 24 and desce d to the first position thereof for the purise of a repetition of the operation, as will be fully understood.

Having thus described my invention, I claim as new and desire to secureby Letters Patenty l.
